How to Tighten Garage Door Chain

A garage door chain is typically tensioned by turning a screw that pulls the chain taut. Garage door chains should be tightened periodically to prevent them from becoming loose and eventually breaking.

If you have a garage door that needs to be tightened, this post will teach you how to tighten garage door chain! There are two main types of garage doors wood and metal. Metal doors should not often need tightening because they’re typically more durable than wood ones.

Step by Step Guide: How to Tighten Garage Door Chain

Step 1:

Remove the cover on your chain to expose the sprocket and screw. You should see a screw and a metal, silver-colored sprocket with teeth around it that are attached to the end of the chain. The ends of chains can come in different types depending on how they form one long chain. If your chain has a hook that connects to the sprocket, you need to leave the cover because there is not enough room for a screwdriver through the opening.

Step 2:

Depending on what kind of spring system your door has, you can tighten it with either an Allen wrench or an adjustable wrench. If you are using a flathead screwdriver to tighten the doors, you’ll use an adjustable wrench because there is a spring that will be compressed. If your door has a torsion spring, you can easily access it with an Allen wrench or flathead screwdriver.

Step 3:

Tighten the chain by turning the screw counterclockwise until it’s tight and bring the ends together. If your door has a spring system, the chain will be loose again with the next opening and closing of the door.

Step 4:

Securely attach the two ends of the chain so they can’t come apart. One way you can do this is to use pliers to squeeze or curl up one end of the chain and attach the sprocket to it or wrap a small clamp around one end of the chain.

Step 5:

Check the tightness of your door several times each day for about a week after you take the cover off. This will ensure that the chain is tightened properly and doesn’t become loose.

Step 6:

Once you are sure that it has been securely tightened, use a hammer to flatten the end of both screws on metal doors so they can’t be used as a handle that can be removed.

Step 7:

If your garage door chain is broken, you will need to replace it before setting up your spring again. You can either purchase a new chain or use the one from the old door if it’s still intact. If you buy a new chain, be sure that you are purchasing screws that fit your sprocket to avoid damaging them while trying to attach it.

8 Reasons Why Garage Door Chain Loosen Overtime

  • If you use your garage door a lot, the frequency of opening and closing causes the chain to loosen.
  • Winterizing your garage removes all air from it, causing a vacuum that loosens the chain when you open and closes the door.
  • A bent screwdriver or an Allen wrench can both cause damage to your sprocket and loosen the chain.
  • Bent or missing teeth in your sprocket can also cause damage to the screwdriver and lose your garage door chain.
  • If you are using an old, rusty screwdriver instead of a new one that has been properly aligned, it will wear quickly and bend out of shape, causing damage to your spring system.
  • If your garage door chain is broken from the sprocket, it could be because of a screw that became loose and fell off.
  • If you have tried to loosen the chain once already and failed, try again with an Allen wrench instead of a flathead one so you won’t damage your sprocket if it’s bent or rusty.
  • Having different-sized springs can cause tension in your chain to become uneven and loosen it more often.

Some Tips To Maintain Garage Door Chain

  • Wipe off the garage door chain with a suitable cleaning agent regularly and maintain it in good condition.
  • Store the garage door chain properly if you do not use it for a long time to avoid its rusting.
  • Inspect the garage door chain regularly to eliminate possible accidents due to rusty or loose garage door chains.
  • Check the garage door chain regularly for possible damages before using it to avoid injury from accidents.
  • Replace the garage door chain if it is damaged or no longer has a firm tension on it and replace it with a new one in good condition and can be used safely.

5 Alternative Ways To Tighten Garage Door Chain

  • Check if the track is bent: If it is, it’s necessary to fix them manually or contact your local garage door service. Bent tracks won’t let you open and close the doors easily.
  • Lubricate the rollers: Stop lifting and lowering the door when you need to lubricate the roller wheels. You can do this with the assistance of any silicone lubricating. Don’t just use one kind; change it as the old ones become thin and watery.
  • Avoid using a broomstick: Some people will use a broomstick to lift or lower their garage door chain, which only works for a short time. You can use them for a longer period of time if you are using an aluminum broomstick. If you have noticed that this is not stable, you must get help from other people who could exert more force.
  • Place the bar in your garage door rollers: This will provide additional support and lets you raise or lower the door slower. This will also help stabilize the door’s weight so that it won’t cause additional wear and tear in your garage door rollers, which might lead to an expensive repair cost.
  • Keep away from using a vacuum cleaner: You may find that adding these appliances to your routine maintenance is very effective, but they can be harmful. It is advisable to remove the debris within the garage before closing it.
